construction and cheap to manufacture, and

which'may be quickly and easily secured in place upon the chair. Afurther object of the invention is to provide positive means forpreventing the rearward creeping of the chair seat.

A further object of the invention is to so construct the chair seat andarrange the same in place that there is no tendency for the elements ofthe chair seat to break.

A further object of the invention is to provide a chair seat which` willpossess a substantial degree of yielding action.

Other objects and advantages of the invention will be apparent duringthe course of the following description.

In the accompanying drawing, forming a part of this application, and inwhich like numerals are employed to designate like parts throughout thesame,

Figure 1 is a perspective view of a chair embodying my invention,

' Figure 2 is a central vertical longitudinal sec- I' tion through thesame,

Figure 3 is a horizontal section taken on line 3 3 of Figure 2,

Figure 4 is a transverse vertical section taken on line 4 4 of Figure 3,and

Figure 5 is an exploded perspective view of the seat.

In'the drawing, wherein for the purpose of illustration is shown apreferred embodiment of my invention, the numerals I0 and II designatethe rear and front posts or uprights of the chair,

, which are rigidly connected by upper side rounds I2, a front round I3and` a rear round I4, .and any suitable number of additional rounds I5,as shown. The uprights or posts I0 project above the upper rounds andare connected by slats I6 to form the back of the chair.

My improved seat embodies a forward attaching rail I1 and a rearattaching rail I8, which are rigid, and these rails are provided upontheir inner longitudinal edges with grooves I9 and 20,

respectively, which are of substantial depth. These grooves receive theends of slats 2I formed of woodor the like, and these slats aresufficiently stiff to support the weight of the user of the chair, btpossess substantial resiliency. These slats are preferablylongitudinally curved in a horizontal plane. The ends of these slatsproject into the grooves I9 and 20as stated, and these ends are securelyretained within the grooves and attached to the rails I1 and I8 by nails22, which are-driven upwardly through the bottom faces of the rails, andthe ends of the nails terminate below the upper surface of the rails. Ithas been found that the nails alone are suillcient to retain the slatsproperly attached to the rails, but if desired, the ends ot the slatsmay also be glued to the rails, within the grooves. The slats -2I may bearranged in parallel relation or they may 10 converge rearwardly, tocorrespond with the shapel of the chair, as shown.

The seat has its forward and rear rails I1 and I8 arranged above and incontact with the rounds I3 and I4, while the outer side slats 2l areprefer- 15 ably arranged parallel with the side rounds I2, whereby theside rounds form, in eiect, a continuation of the seat. The slats 2l arelongitudinally bowed with their upper surfaces depressed. as shown. Theforward rail I1 has its opposite ends cut upon a transverse curve toprovide curved shoulders or lips 23, which engages with the upper endsof the forward uprights or posts II in advance of the same, sufficientlyto produce wedging action, if the seat should move-rearwardly withrespect to the forward uprights. This is an important feature of theinvention, as there is a tendency for the seat to shift rearwardly withrespect to the body of achair, during the use of the chair. The forwardrail I1 is attached to 30 the upper round I3 by means of nails 24 or thelike, which vare preferably driven downwardly through the upper surfaceof the,v rail into the upper forward round I3, and preferably passthrough the central longitudinal axis of the 35 round. Particularattention is called to the fact that the slats project into the grooveI9 sunlciently so that they extend over the point of contact between therail and round I3, so that the lower thin portion I1 of the rail,produced by the 40 grooveis properly supported, and there is noliability of the same breaking o, when the chair is subjected to anexcessive strain. The rear rail I8 is attached to the round I4 bysimilar nails 25 or the like, driven in position in' a similar man- 45ner, and the arrangement of the ends of the slats is such that the thinportion I8 of the rail I8 is properly supported by the round againstbreaking action. The'nails 24 and 25 have been found ample for holdingthe seat in position, operating 50 in conjunction with the engaging lipsor anges 23, and these nails produceV a somewhat yielding connectionbetween the rails I1 and I8 and the rounds I3 and I4, respectively,whereby a slight rollinga'ction of the rails upon their longi- 65tudinal axes, upon the rounds, may occur when weight is applied to theseat.

`Whil I have shown my invention as embodied' in a str ight chair, it isin no sense restricted to this embodiment, as it may be embodied in arocking chair.

In view of the foregoing description, it is believed that the mode ofassembling the chair is obvious and that the chair is used in theordinary manner. As stated, the slats 2| are sufficiently stiif toproperly support the user of the chair, but are substantially'resilientso that a slight yielding action will occur, when weight is applied tothe seat. Since the rails l1 and I8 are also yieldingly secured to therounds, these rails may partake of a limited rocking action upon therounds, when the slats 2| flex vor yield, in a limited manner, asstated.

It is to be understood that the form of my invention herewith shown anddescribed is to be taken as a preferred example of the same, and thatvarious changes in the shape, size and arrangement of parts may beresorted to without departing from the spirit of my invention or thescope of the subjoined claims.

Having thus described my invention, I claim:
